Hii Subham,

Hope you are doing good.

Yes, Ofcourse BCA students are eligible for CSE BTech.

Eligibility criteria for Cse::

10+2 with Physics, Chemistry, and Mathematics + Entrance Exam valid for the university

Fee Structure:: 50k - 4/5lpa or more ( depends on Universities public or private )

BCA students can take admission in CSE (CS/IT) after completing BCA through lateral entry which is from 2nd year.

Hopefully this cleared your query.

Best wishes for future endeavours.
